Looking to replace my D16Y8 with a different engine. If all I can find is an older D15 or D16, can I transplant the Y8 hardware onto it? Would my Y8 head transplant over to one of those engines if it were still good? I say still good cause my buddy sent the #3 connecting rod through the oil pan. The block is bad, and I have yet to take the head off yet. Just weighing my options here. I seem to only be finding older engines here in Germany.
